摘要
Abstract
In order to determine the different polarity of solvent licorice extract on bacteriostatic action of plant pathogenic bacteria, the growth rate method was used to study the bacteriostatic effect of 6 licorice solvent extract to Fusarium graminearum,Fusarium oxysporum,Fusarium semitectum,Alternaria solani and Rhizoctonia solani. The results showed that the extraction ratio and the bacteriostatic effect of the different extraction solvents had obvious differences. The ethyl acetate and acetone extracts had better antibacterial activity than other solvents,and the bacteriostatic effect to Fusarium oxysporum are 82.64% and 83.13% respectively. So the antibacterial substances could be the licorice flavonoids.关键词
